Activating the sensor/inserting the batteries
Battery type:
The combined sensor is operated on four AAA (LR 03) alkaline batteries (not included). Do not use
zinc/carbon batteries (R 03) or rechargeable batteries.
To avoid damaging the electronics through electrostatic discharge, you must comply with the safety
precautions for electrostatically sensitive devices when changing the battery.
Inserting (replacing) the batteries
1. Detach the combined sensor from the base plate by turning the unit approx. 45° clockwise (Fig. C).
2. Remove any old batteries. Wait about 2 minutes before inserting the new batteries. Make sure they
are the right way round (Fig. D).
3. Attach the combined sensor to the base plate again by turning the unit about 45° anticlockwise until
it clicks in place.
4. For the first 30 seconds after batteries are inserted the combined sensor sends special
programming telegrams.

Flat battery indicator:
The LED integrated behind the sensor window (Fig. A1) can only be seen in darkness. It flashes three
times whenever a transmission is made.
If the LED flashes about ten times, this indicates that the batteries are almost flat (LowBatt) and
have to be replaced.
Important.
Keep batteries away from children. If a battery is swallowed, seek medical attention immediately.
Replace the batteries with ones of the same type.
Old batteries should be removed immediately and disposed of properly.
